I recently acquired a Sony Vaio PCG-505TR with a 300mhz Pentium and Windows 98 in a lot. The computer is in overall good cosmetic condition without anything missing. However, the computer will not turn on when I use my Targus APA68US. The other computer in the lot, a Fujitsu Lifebook 735Dx works fine with this power adapter. The only differnece is that the Fujitsu Lifebook is DC 16V 2.7A, while the Vaio is 16V 2.0A. Can someone help me, I had a similar Vaio back in the day.

Thank You rotor123, I tried the adapter alone without the battery the machine did a harddrive spinning noise that is very quiet. When I put in the cracked the battery it gives a blinking orange light. Nothing happens, is this a motherboard faliure or a power adpter issue? I found a power adpater on eBay. Thanks.

I hate to say this but the fact that You are feeding it the proper voltage and You seem to hear a noise once You remove the battery and turn it on, In my mind that eliminates the AC adapter and puts the fault inside the computer. I suspect that buying a AC adapter for it would be a waste of money.

Good Luck

You need to find the Service manual online or with any luck a how to disassemble video on YouTube. Are You sure it is worth the trouble? 300Mhz Pentium CPU. Are You sure the screen is good and all the rest of the hardware? Since it does not turn on I see no way to tell if the rest of the computer is good.

Good Luck

rotor123, I force removed the bezel and broke it and go into it. It is a clear motherboard faliure becuase a small circuit fell off the motherboard when I removed it. I found one on eBay for parts and the motherboard is good, so I can replace it. Thanks rotor123, you may remove or close this thread.
